*Electrical data at 25C (77F). Actual wattage may differ by +/-10%.
1 - Lumen maintenance values at 25C are calculated per TM-21 based on LM-80 data and in-situ testing.2 - In accordance with IESNA TM-21-11, Projected Values represent interpolated value based on time
durations that are within six times the IESNA LM-80-08 total test duration for the device under testing.
3 - In accordance with IESNA TM-21-11, Calculated Values represent time durations that exceed six times the IESNA LM-80-08 total test duration for the device under testing.

ACCESSORY ORDERING INFORMATIONDescription Order Number Order Number
FOOTNOTES:1 - Photocell must be ordered separately. See Accessories. 2 - Factory installed PCR option required. See Options. 3 - Fusing must be located in hand hole of pole.4 - These photocells provide Dusk/Dawn, on-off control only. Consult factory for alternate photocells providing additional functionality.
5 - Order poles with 3" reduced drilling pattern. For PT mounting configurations other than D180, consult factory. Order one bracket per fixture6 - Consists of a daylight & motion dual sensor. Light levels are field adjustable via a handheld remote configurator tool. Not available PCR 7P.
ControlsOccupancy Sensor / Daylight Sensor (IMS)Optional integral passive infrared motion and daylight sensor activates switching of luminaire light levels. Standard Factory settings: High level light is activated and increased to full bright upon detection of motion. Low light level (30% maximum drive current) is activated when target zone is absent of motion activity for ~5 minutes. Sensor has a detection cone of approxi-mately 45°, see coverage diagram. Optional configurator tool allows for easy and safe programming of each luminaire from the ground level.
